cmdSetDepthBias Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which the command will be recorded.

-> ("depthBiasConstantFactor" ::: Float)

depthBiasConstantFactor is a scalar factor controlling the constant depth value added to each fragment.

-> ("depthBiasClamp" ::: Float)

depthBiasClamp is the maximum (or minimum) depth bias of a fragment.

-> ("depthBiasSlopeFactor" ::: Float)

depthBiasSlopeFactor is a scalar factor applied to a fragment’s slope in depth bias calculations.

-> io () 

vkCmdSetDepthBias - Set the depth bias dynamic state

Description

If depthBiasEnable is FALSE, no depth bias is applied and the fragment’s depth values are unchanged.

depthBiasSlopeFactor scales the maximum depth slope of the polygon, and depthBiasConstantFactor scales an implementation-dependent constant that relates to the usable resolution of the depth buffer. The resulting values are summed to produce the depth bias value which is then clamped to a minimum or maximum value specified by depthBiasClamp. depthBiasSlopeFactor, depthBiasConstantFactor, and depthBiasClamp can each be positive, negative, or zero.

The maximum depth slope m of a triangle is

\[m = \sqrt{ \left({{\partial z_f} \over {\partial x_f}}\right)^2 + \left({{\partial z_f} \over {\partial y_f}}\right)^2}\]

where (xf, yf, zf) is a point on the triangle. m may be approximated as

\[m = \max\left( \left| { {\partial z_f} \over {\partial x_f} } \right|, \left| { {\partial z_f} \over {\partial y_f} } \right| \right).\]

The minimum resolvable difference r is an implementation-dependent parameter that depends on the depth buffer representation. It is the smallest difference in framebuffer coordinate z values that is guaranteed to remain distinct throughout polygon rasterization and in the depth buffer. All pairs of fragments generated by the rasterization of two polygons with otherwise identical vertices, but zf values that differ by r, will have distinct depth values.

For fixed-point depth buffer representations, r is constant throughout the range of the entire depth buffer. For floating-point depth buffers, there is no single minimum resolvable difference. In this case, the minimum resolvable difference for a given polygon is dependent on the maximum exponent, e, in the range of z values spanned by the primitive. If n is the number of bits in the floating-point mantissa, the minimum resolvable difference, r, for the given primitive is defined as

  • r = 2e-n

If a triangle is rasterized using the POLYGON_MODE_FILL_RECTANGLE_NV polygon mode, then this minimum resolvable difference may not be resolvable for samples outside of the triangle, where the depth is extrapolated.

If no depth buffer is present, r is undefined.

The bias value o for a polygon is

[begin{aligned} o &= mathrm{dbclamp}( m times mathtt{depthBiasSlopeFactor} + r times mathtt{depthBiasConstantFactor} ) -- text{where} &quad mathrm{dbclamp}(x) =

cmdBindDescriptorSets Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer that the descriptor sets will be bound to.

-> PipelineBindPoint

pipelineBindPoint is a PipelineBindPoint indicating the type of the pipeline that will use the descriptors. There is a separate set of bind points for each pipeline type, so binding one does not disturb the others.

-> PipelineLayout

layout is a PipelineLayout object used to program the bindings.

-> ("firstSet" ::: Word32)

-> ("descriptorSets" ::: Vector DescriptorSet)

pDescriptorSets is a pointer to an array of handles to DescriptorSet objects describing the descriptor sets to write to.

-> ("dynamicOffsets" ::: Vector Word32)

pDynamicOffsets is a pointer to an array of uint32_t values specifying dynamic offsets.

-> io () 

vkCmdBindDescriptorSets - Binds descriptor sets to a command buffer

Description

cmdBindDescriptorSets causes the sets numbered [firstSet.. firstSet+descriptorSetCount-1] to use the bindings stored in pDescriptorSets[0..descriptorSetCount-1] for subsequent bound pipeline commands set by pipelineBindPoint. Any bindings that were previously applied via these sets are no longer valid.

Once bound, a descriptor set affects rendering of subsequent commands that interact with the given pipeline type in the command buffer until either a different set is bound to the same set number, or the set is disturbed as described in Pipeline Layout Compatibility.

A compatible descriptor set must be bound for all set numbers that any shaders in a pipeline access, at the time that a draw or dispatch command is recorded to execute using that pipeline. However, if none of the shaders in a pipeline statically use any bindings with a particular set number, then no descriptor set need be bound for that set number, even if the pipeline layout includes a non-trivial descriptor set layout for that set number.

If any of the sets being bound include dynamic uniform or storage buffers, then pDynamicOffsets includes one element for each array element in each dynamic descriptor type binding in each set. Values are taken from pDynamicOffsets in an order such that all entries for set N come before set N+1; within a set, entries are ordered by the binding numbers in the descriptor set layouts; and within a binding array, elements are in order. dynamicOffsetCount must equal the total number of dynamic descriptors in the sets being bound.

The effective offset used for dynamic uniform and storage buffer bindings is the sum of the relative offset taken from pDynamicOffsets, and the base address of the buffer plus base offset in the descriptor set. The range of the dynamic uniform and storage buffer bindings is the buffer range as specified in the descriptor set.

Each of the pDescriptorSets must be compatible with the pipeline layout specified by layout. The layout used to program the bindings must also be compatible with the pipeline used in subsequent bound pipeline commands with that pipeline type, as defined in the Pipeline Layout Compatibility section.

The descriptor set contents bound by a call to cmdBindDescriptorSets may be consumed at the following times:

  • For descriptor bindings created with the DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT bit set, the contents may be consumed when the command buffer is submitted to a queue, or during shader execution of the resulting draws and dispatches, or any time in between. Otherwise,
  • during host execution of the command, or during shader execution of the resulting draws and dispatches, or any time in between.

Thus, the contents of a descriptor set binding must not be altered (overwritten by an update command, or freed) between the first point in time that it may be consumed, and when the command completes executing on the queue.

The contents of pDynamicOffsets are consumed immediately during execution of cmdBindDescriptorSets. Once all pending uses have completed, it is legal to update and reuse a descriptor set.

Valid Usage

  • Each element of pDescriptorSets must have been allocated with a DescriptorSetLayout that matches (is the same as, or identically defined as) the DescriptorSetLayout at set n in layout, where n is the sum of firstSet and the index into pDescriptorSets
  • dynamicOffsetCount must be equal to the total number of dynamic descriptors in pDescriptorSets
  • The sum of firstSet and descriptorSetCount must be less than or equal to PipelineLayoutCreateInfo::setLayoutCount provided when layout was created
  • pipelineBindPoint must be supported by the commandBuffer’s parent CommandPool’s queue family
  • Each element of pDynamicOffsets which corresponds to a descriptor binding with type DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC must be a multiple of PhysicalDeviceLimits::minUniformBufferOffsetAlignment
  • Each element of pDynamicOffsets which corresponds to a descriptor binding with type DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC must be a multiple of PhysicalDeviceLimits::minStorageBufferOffsetAlignment
  • For each dynamic uniform or storage buffer binding in pDescriptorSets, the sum of the effective offset, as defined above, and the range of the binding must be less than or equal to the size of the buffer

Valid Usage (Implicit)

  • pipelineBindPoint must be a valid PipelineBindPoint value
  • layout must be a valid PipelineLayout handle
  • pDescriptorSets must be a valid pointer to an array of descriptorSetCount valid DescriptorSet handles
  • If dynamicOffsetCount is not 0, pDynamicOffsets must be a valid pointer to an array of dynamicOffsetCount uint32_t values
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
  • descriptorSetCount must be greater than 0
  • Each of commandBuffer, layout, and the elements of pDescriptorSets must have been created, allocated, or retrieved from the same Device

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

vkCmdBindVertexBuffers - Bind vertex buffers to a command buffer

Description

The vertex input binding is updated to start at the offset indicated by pOffsets[i] from the start of the buffer pBuffers[i]. All vertex input attributes that use each of these bindings will use these updated addresses in their address calculations for subsequent draw commands. If the nullDescriptor feature is enabled, elements of pBuffers can be NULL_HANDLE, and can be used by the vertex shader. If a vertex input attribute is bound to a vertex input binding that is NULL_HANDLE, the values taken from memory are considered to be zero, and missing G, B, or A components are filled with (0,0,1).

Description

When the command is executed, primitives are assembled using the current primitive topology and indexCount vertices whose indices are retrieved from the index buffer.

Subsequent index values are retrieved from consecutive locations in the index buffer. Indices are first compared to the primitive restart value, then zero extended to 32 bits (if the indexType is INDEX_TYPE_UINT8_EXT or INDEX_TYPE_UINT16) and have vertexOffset added to them, before being supplied as the vertexIndex value.

The primitives are drawn instanceCount times with instanceIndex starting with firstInstance and increasing sequentially for each instance. The assembled primitives execute the bound graphics pipeline.

vkCmdCopyImage - Copy data between images

Description

Each region in pRegions is copied from the source image to the same region of the destination image. srcImage and dstImage can be the same image or alias the same memory.

The formats of srcImage and dstImage must be compatible. Formats are compatible if they share the same class, as shown in the Compatible Formats table. Depth/stencil formats must match exactly.

If the format of srcImage or dstImage is a multi-planar image format, regions of each plane to be copied must be specified separately using the srcSubresource and dstSubresource members of the ImageCopy structure. In this case, the aspectMask of the srcSubresource or dstSubresource that refers to the multi-planar image must be IMAGE_ASPECT_PLANE_0_BIT, IMAGE_ASPECT_PLANE_1_BIT, or IMAGE_ASPECT_PLANE_2_BIT. For the purposes of cmdCopyImage, each plane of a multi-planar image is treated as having the format listed in https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#formats-compatible-planes for the plane identified by the aspectMask of the corresponding subresource. This applies both to Format and to coordinates used in the copy, which correspond to texels in the plane rather than how these texels map to coordinates in the image as a whole.

Note

For example, the IMAGE_ASPECT_PLANE_1_BIT plane of a FORMAT_G8_B8R8_2PLANE_420_UNORM image is compatible with an image of format FORMAT_R8G8_UNORM and (less usefully) with the IMAGE_ASPECT_PLANE_0_BIT plane of an image of format FORMAT_G10X6_B10X6_R10X6_3PLANE_420_UNORM_3PACK16, as each texel is 2 bytes in size.

cmdCopyImage allows copying between size-compatible compressed and uncompressed internal formats. Formats are size-compatible if the texel block size of the uncompressed format is equal to the texel block size of the compressed format. Such a copy does not perform on-the-fly compression or decompression. When copying from an uncompressed format to a compressed format, each texel of uncompressed data of the source image is copied as a raw value to the corresponding compressed texel block of the destination image. When copying from a compressed format to an uncompressed format, each compressed texel block of the source image is copied as a raw value to the corresponding texel of uncompressed data in the destination image. Thus, for example, it is legal to copy between a 128-bit uncompressed format and a compressed format which has a 128-bit sized compressed texel block representing 4×4 texels (using 8 bits per texel), or between a 64-bit uncompressed format and a compressed format which has a 64-bit sized compressed texel block representing 4×4 texels (using 4 bits per texel).

When copying between compressed and uncompressed formats the extent members represent the texel dimensions of the source image and not the destination. When copying from a compressed image to an uncompressed image the image texel dimensions written to the uncompressed image will be source extent divided by the compressed texel block dimensions. When copying from an uncompressed image to a compressed image the image texel dimensions written to the compressed image will be the source extent multiplied by the compressed texel block dimensions. In both cases the number of bytes read and the number of bytes written will be identical.

Copying to or from block-compressed images is typically done in multiples of the compressed texel block size. For this reason the extent must be a multiple of the compressed texel block dimension. There is one exception to this rule which is required to handle compressed images created with dimensions that are not a multiple of the compressed texel block dimensions: if the srcImage is compressed, then:

  • If extent.width is not a multiple of the compressed texel block width, then (extent.width + srcOffset.x) must equal the image subresource width.
  • If extent.height is not a multiple of the compressed texel block height, then (extent.height + srcOffset.y) must equal the image subresource height.
  • If extent.depth is not a multiple of the compressed texel block depth, then (extent.depth + srcOffset.z) must equal the image subresource depth.

Similarly, if the dstImage is compressed, then:

  • If extent.width is not a multiple of the compressed texel block width, then (extent.width + dstOffset.x) must equal the image subresource width.
  • If extent.height is not a multiple of the compressed texel block height, then (extent.height + dstOffset.y) must equal the image subresource height.
  • If extent.depth is not a multiple of the compressed texel block depth, then (extent.depth + dstOffset.z) must equal the image subresource depth.

This allows the last compressed texel block of the image in each non-multiple dimension to be included as a source or destination of the copy.

“_422” image formats that are not multi-planar are treated as having a 2×1 compressed texel block for the purposes of these rules.

cmdCopyImage can be used to copy image data between multisample images, but both images must have the same number of samples.

vkCmdBlitImage - Copy regions of an image, potentially performing format conversion,

Description

cmdBlitImage must not be used for multisampled source or destination images. Use cmdResolveImage for this purpose.

As the sizes of the source and destination extents can differ in any dimension, texels in the source extent are scaled and filtered to the destination extent. Scaling occurs via the following operations:

  • For each destination texel, the integer coordinate of that texel is converted to an unnormalized texture coordinate, using the effective inverse of the equations described in unnormalized to integer conversion:

    • ubase = i + ½
    • vbase = j + ½
    • wbase = k + ½

  • These base coordinates are then offset by the first destination offset:

    • uoffset = ubase - xdst0
    • voffset = vbase - ydst0
    • woffset = wbase - zdst0
    • aoffset = a - baseArrayCountdst

  • The scale is determined from the source and destination regions, and applied to the offset coordinates:

    • scaleu = (xsrc1 - xsrc0) / (xdst1 - xdst0)
    • scalev = (ysrc1 - ysrc0) / (ydst1 - ydst0)
    • scalew = (zsrc1 - zsrc0) / (zdst1 - zdst0)
    • uscaled = uoffset × scaleu
    • vscaled = voffset × scalev
    • wscaled = woffset × scalew

  • Finally the source offset is added to the scaled coordinates, to determine the final unnormalized coordinates used to sample from srcImage:

    • u = uscaled + xsrc0
    • v = vscaled + ysrc0
    • w = wscaled + zsrc0
    • q = mipLevel
    • a = aoffset + baseArrayCountsrc

These coordinates are used to sample from the source image, as described in Image Operations chapter, with the filter mode equal to that of filter, a mipmap mode of SAMPLER_MIPMAP_MODE_NEAREST and an address mode of SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE. Implementations must clamp at the edge of the source image, and may additionally clamp to the edge of the source region.

Note

Due to allowable rounding errors in the generation of the source texture coordinates, it is not always possible to guarantee exactly which source texels will be sampled for a given blit. As rounding errors are implementation dependent, the exact results of a blitting operation are also implementation dependent.

Blits are done layer by layer starting with the baseArrayLayer member of srcSubresource for the source and dstSubresource for the destination. layerCount layers are blitted to the destination image.

When blitting 3D textures, slices in the destination region bounded by dstOffsets[0].z and dstOffsets[1].z are sampled from slices in the source region bounded by srcOffsets[0].z and srcOffsets[1].z. If the filter parameter is FILTER_LINEAR then the value sampled from the source image is taken by doing linear filtering using the interpolated z coordinate represented by w in the previous equations. If the filter parameter is FILTER_NEAREST then the value sampled from the source image is taken from the single nearest slice, with an implementation-dependent arithmetic rounding mode.

The following filtering and conversion rules apply:

  • Integer formats can only be converted to other integer formats with the same signedness.
  • No format conversion is supported between depth/stencil images. The formats must match.
  • Format conversions on unorm, snorm, unscaled and packed float formats of the copied aspect of the image are performed by first converting the pixels to float values.
  • For sRGB source formats, nonlinear RGB values are converted to linear representation prior to filtering.
  • After filtering, the float values are first clamped and then cast to the destination image format. In case of sRGB destination format, linear RGB values are converted to nonlinear representation before writing the pixel to the image.

Signed and unsigned integers are converted by first clamping to the representable range of the destination format, then casting the value.

vkCmdUpdateBuffer - Update a buffer’s contents from host memory

Description

dataSize must be less than or equal to 65536 bytes. For larger updates, applications can use buffer to buffer copies.

Note

Buffer updates performed with cmdUpdateBuffer first copy the data into command buffer memory when the command is recorded (which requires additional storage and may incur an additional allocation), and then copy the data from the command buffer into dstBuffer when the command is executed on a device.

The additional cost of this functionality compared to buffer to buffer copies means it is only recommended for very small amounts of data, and is why it is limited to only 65536 bytes.

Applications can work around this by issuing multiple cmdUpdateBuffer commands to different ranges of the same buffer, but it is strongly recommended that they should not.

The source data is copied from the user pointer to the command buffer when the command is called.

cmdUpdateBuffer is only allowed outside of a render pass. This command is treated as “transfer” operation, for the purposes of synchronization barriers. The BUFFER_USAGE_TRANSFER_DST_BIT must be specified in usage of BufferCreateInfo in order for the buffer to be compatible with cmdUpdateBuffer.

  • dataSize must be less than or equal to the size of dstBuffer minus dstOffset
  • dstBuffer must have been created with BUFFER_USAGE_TRANSFER_DST_BIT usage flag

vkCmdClearAttachments - Clear regions within bound framebuffer attachments

Description

cmdClearAttachments can clear multiple regions of each attachment used in the current subpass of a render pass instance. This command must be called only inside a render pass instance, and implicitly selects the images to clear based on the current framebuffer attachments and the command parameters.

If the render pass has a fragment density map attachment, clears follow the operations of fragment density maps as if each clear region was a primitive which generates fragments. The clear color is applied to all pixels inside each fragment’s area regardless if the pixels lie outside of the clear region. Clears may have a different set of supported fragment areas than draws.

Unlike other clear commands, cmdClearAttachments executes as a drawing command, rather than a transfer command, with writes performed by it executing in rasterization order. Clears to color attachments are executed as color attachment writes, by the PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT stage. Clears to depth/stencil attachments are executed as depth writes and writes by the PIPELINE_STAGE_EARLY_FRAGMENT_TESTS_BIT and PIPELINE_STAGE_LATE_FRAGMENT_TESTS_BIT stages.

Valid Usage

vkCmdResolveImage - Resolve regions of an image

Description

During the resolve the samples corresponding to each pixel location in the source are converted to a single sample before being written to the destination. If the source formats are floating-point or normalized types, the sample values for each pixel are resolved in an implementation-dependent manner. If the source formats are integer types, a single sample’s value is selected for each pixel.

vkCmdResetEvent - Reset an event object to non-signaled state

Description

When cmdResetEvent is submitted to a queue, it defines an execution dependency on commands that were submitted before it, and defines an event unsignal operation which resets the event to the unsignaled state.

The first synchronization scope includes all commands that occur earlier in submission order. The synchronization scope is limited to operations on the pipeline stages determined by the source stage mask specified by stageMask.

vkCmdWaitEvents - Wait for one or more events and insert a set of memory

Description

When cmdWaitEvents is submitted to a queue, it defines a memory dependency between prior event signal operations on the same queue or the host, and subsequent commands. cmdWaitEvents must not be used to wait on event signal operations occurring on other queues.

The first synchronization scope only includes event signal operations that operate on members of pEvents, and the operations that happened-before the event signal operations. Event signal operations performed by cmdSetEvent that occur earlier in submission order are included in the first synchronization scope, if the logically latest pipeline stage in their stageMask parameter is logically earlier than or equal to the logically latest pipeline stage in srcStageMask. Event signal operations performed by setEvent are only included in the first synchronization scope if PIPELINE_STAGE_HOST_BIT is included in srcStageMask.

The second synchronization scope includes all commands that occur later in submission order. The second synchronization scope is limited to operations on the pipeline stages determined by the destination stage mask specified by dstStageMask.

The first access scope is limited to access in the pipeline stages determined by the source stage mask specified by srcStageMask. Within that, the first access scope only includes the first access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the first access scope includes no accesses.

The second access scope is limited to access in the pipeline stages determined by the destination stage mask specified by dstStageMask. Within that, the second access scope only includes the second access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the second access scope includes no accesses.

Note

cmdWaitEvents is used with cmdSetEvent to define a memory dependency between two sets of action commands, roughly in the same way as pipeline barriers, but split into two commands such that work between the two may execute unhindered.

Unlike cmdPipelineBarrier, a queue family ownership transfer cannot be performed using cmdWaitEvents.

Note

Applications should be careful to avoid race conditions when using events. There is no direct ordering guarantee between a cmdResetEvent command and a cmdWaitEvents command submitted after it, so some other execution dependency must be included between these commands (e.g. a semaphore).

vkCmdPipelineBarrier - Insert a memory dependency

Description

When cmdPipelineBarrier is submitted to a queue, it defines a memory dependency between commands that were submitted before it, and those submitted after it.

If cmdPipelineBarrier was recorded outside a render pass instance, the first synchronization scope includes all commands that occur earlier in submission order. If cmdPipelineBarrier was recorded inside a render pass instance, the first synchronization scope includes only commands that occur earlier in submission order within the same subpass. In either case, the first synchronization scope is limited to operations on the pipeline stages determined by the source stage mask specified by srcStageMask.

If cmdPipelineBarrier was recorded outside a render pass instance, the second synchronization scope includes all commands that occur later in submission order. If cmdPipelineBarrier was recorded inside a render pass instance, the second synchronization scope includes only commands that occur later in submission order within the same subpass. In either case, the second synchronization scope is limited to operations on the pipeline stages determined by the destination stage mask specified by dstStageMask.

The first access scope is limited to access in the pipeline stages determined by the source stage mask specified by srcStageMask. Within that, the first access scope only includes the first access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the first access scope includes no accesses.

The second access scope is limited to access in the pipeline stages determined by the destination stage mask specified by dstStageMask. Within that, the second access scope only includes the second access scopes defined by elements of the pMemoryBarriers, pBufferMemoryBarriers and pImageMemoryBarriers arrays, which each define a set of memory barriers. If no memory barriers are specified, then the second access scope includes no accesses.

If dependencyFlags includes DEPENDENCY_BY_REGION_BIT, then any dependency between framebuffer-space pipeline stages is framebuffer-local - otherwise it is framebuffer-global.

Note that cmdEndQuery is *not* called if an exception is thrown by the inner action.

cmdEndQuery Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which this command will be recorded.

-> QueryPool

queryPool is the query pool that is managing the results of the query.

-> ("query" ::: Word32)

query is the query index within the query pool where the result is stored.

-> io () 

vkCmdEndQuery - Ends a query

Description

Calling cmdEndQuery is equivalent to calling cmdEndQueryIndexedEXT with the index parameter set to zero.

As queries operate asynchronously, ending a query does not immediately set the query’s status to available. A query is considered finished when the final results of the query are ready to be retrieved by getQueryPoolResults and cmdCopyQueryPoolResults, and this is when the query’s status is set to available.

Once a query is ended the query must finish in finite time, unless the state of the query is changed using other commands, e.g. by issuing a reset of the query.

Valid Usage

  • All queries used by the command must be active

Valid Usage (Implicit)

  • queryPool must be a valid QueryPool handle
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
  • Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same Device

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

cmdResetQueryPool Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which this command will be recorded.

-> QueryPool

queryPool is the handle of the query pool managing the queries being reset.

-> ("firstQuery" ::: Word32)

firstQuery is the initial query index to reset.

-> ("queryCount" ::: Word32)

queryCount is the number of queries to reset.

-> io () 

vkCmdResetQueryPool - Reset queries in a query pool

Description

When executed on a queue, this command sets the status of query indices [firstQuery, firstQuery + queryCount - 1] to unavailable.

If the queryType used to create queryPool was QUERY_TYPE_PERFORMANCE_QUERY_KHR, this command sets the status of query indices [firstQuery, firstQuery + queryCount - 1] to unavailable for each pass of queryPool, as indicated by a call to getPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR.

Note

Because cmdResetQueryPool resets all the passes of the indicated queries, applications must not record a cmdResetQueryPool command for a queryPool created with QUERY_TYPE_PERFORMANCE_QUERY_KHR in a command buffer that needs to be submitted multiple times as indicated by a call to getPhysicalDeviceQueueFamilyPerformanceQueryPassesKHR. Otherwise applications will never be able to complete the recorded queries.

Valid Usage

  • firstQuery must be less than the number of queries in queryPool
  • The sum of firstQuery and queryCount must be less than or equal to the number of queries in queryPool
  • All queries used by the command must not be active
  • If queryPool was created with QUERY_TYPE_PERFORMANCE_QUERY_KHR, this command must not be recorded in a command buffer that, either directly or through secondary command buffers, also contains begin commands for a query from the set of queries [firstQuery, firstQuery + queryCount - 1]

Valid Usage (Implicit)

  • queryPool must be a valid QueryPool handle
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
  • This command must only be called outside of a render pass instance
  • Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same Device

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

cmdWriteTimestamp Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which the command will be recorded.

-> PipelineStageFlagBits

pipelineStage is one of the PipelineStageFlagBits, specifying a stage of the pipeline.

-> QueryPool

queryPool is the query pool that will manage the timestamp.

-> ("query" ::: Word32)

query is the query within the query pool that will contain the timestamp.

-> io () 

vkCmdWriteTimestamp - Write a device timestamp into a query object

Description

cmdWriteTimestamp latches the value of the timer when all previous commands have completed executing as far as the specified pipeline stage, and writes the timestamp value to memory. When the timestamp value is written, the availability status of the query is set to available.

Note

If an implementation is unable to detect completion and latch the timer at any specific stage of the pipeline, it may instead do so at any logically later stage.

Timestamps may only be meaningfully compared if they are written by commands submitted to the same queue.

Note

An example of such a comparison is determining the execution time of a sequence of commands.

If cmdWriteTimestamp is called while executing a render pass instance that has multiview enabled, the timestamp uses N consecutive query indices in the query pool (starting at query) where N is the number of bits set in the view mask of the subpass the command is executed in. The resulting query values are determined by an implementation-dependent choice of one of the following behaviors:

  • The first query is a timestamp value and (if more than one bit is set in the view mask) zero is written to the remaining queries. If two timestamps are written in the same subpass, the sum of the execution time of all views between those commands is the difference between the first query written by each command.
  • All N queries are timestamp values. If two timestamps are written in the same subpass, the sum of the execution time of all views between those commands is the sum of the difference between corresponding queries written by each command. The difference between corresponding queries may be the execution time of a single view.

In either case, the application can sum the differences between all N queries to determine the total execution time.

Valid Usage

  • pipelineStage must be a valid stage for the queue family that was used to create the command pool that commandBuffer was allocated from

Valid Usage (Implicit)

  • pipelineStage must be a valid PipelineStageFlagBits value
  • queryPool must be a valid QueryPool handle
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support transfer, graphics, or compute operations
  • Both of commandBuffer, and queryPool must have been created, allocated, or retrieved from the same Device

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

cmdCopyQueryPoolResults Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer into which this command will be recorded.

-> QueryPool

queryPool is the query pool managing the queries containing the desired results.

-> ("firstQuery" ::: Word32)

firstQuery is the initial query index.

-> ("queryCount" ::: Word32)

queryCount is the number of queries. firstQuery and queryCount together define a range of queries.

-> ("dstBuffer" ::: Buffer)

dstBuffer is a Buffer object that will receive the results of the copy command.

-> ("dstOffset" ::: DeviceSize)

dstOffset is an offset into dstBuffer.

-> ("stride" ::: DeviceSize)

stride is the stride in bytes between results for individual queries within dstBuffer. The required size of the backing memory for dstBuffer is determined as described above for getQueryPoolResults.

-> QueryResultFlags

flags is a bitmask of QueryResultFlagBits specifying how and when results are returned.

-> io () 

vkCmdCopyQueryPoolResults - Copy the results of queries in a query pool to a buffer object

Description

cmdCopyQueryPoolResults is guaranteed to see the effect of previous uses of cmdResetQueryPool in the same queue, without any additional synchronization. Thus, the results will always reflect the most recent use of the query.

flags has the same possible values described above for the flags parameter of getQueryPoolResults, but the different style of execution causes some subtle behavioral differences. Because cmdCopyQueryPoolResults executes in order with respect to other query commands, there is less ambiguity about which use of a query is being requested.

Results for all requested occlusion queries, pipeline statistics queries, transform feedback queries, and timestamp queries are written as 64-bit unsigned integer values if QUERY_RESULT_64_BIT is set or 32-bit unsigned integer values otherwise. Performance queries store results in a tightly packed array whose type is determined by the unit member of the corresponding PerformanceCounterKHR.

If neither of QUERY_RESULT_WAIT_BIT and QUERY_RESULT_WITH_AVAILABILITY_BIT are set, results are only written out for queries in the available state.

If QUERY_RESULT_WAIT_BIT is set, the implementation will wait for each query’s status to be in the available state before retrieving the numerical results for that query. This is guaranteed to reflect the most recent use of the query on the same queue, assuming that the query is not being simultaneously used by other queues. If the query does not become available in a finite amount of time (e.g. due to not issuing a query since the last reset), a ERROR_DEVICE_LOST error may occur.

Similarly, if QUERY_RESULT_WITH_AVAILABILITY_BIT is set and QUERY_RESULT_WAIT_BIT is not set, the availability is guaranteed to reflect the most recent use of the query on the same queue, assuming that the query is not being simultaneously used by other queues. As with getQueryPoolResults, implementations must guarantee that if they return a non-zero availability value, then the numerical results are valid.

If QUERY_RESULT_PARTIAL_BIT is set, QUERY_RESULT_WAIT_BIT is not set, and the query’s status is unavailable, an intermediate result value between zero and the final result value is written for that query.

QUERY_RESULT_PARTIAL_BIT must not be used if the pool’s queryType is QUERY_TYPE_TIMESTAMP.

cmdCopyQueryPoolResults is considered to be a transfer operation, and its writes to buffer memory must be synchronized using PIPELINE_STAGE_TRANSFER_BIT and ACCESS_TRANSFER_WRITE_BIT before using the results.

Valid Usage

  • dstOffset must be less than the size of dstBuffer

Valid Usage (Implicit)

  • queryPool must be a valid QueryPool handle
  • dstBuffer must be a valid Buffer handle
  • flags must be a valid combination of QueryResultFlagBits values
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
  • This command must only be called outside of a render pass instance
  • Each of commandBuffer, dstBuffer, and queryPool must have been created, allocated, or retrieved from the same Device

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

Arguments

:: forall io. MonadIO io

contents specifies how the commands in the next subpass will be provided, in the same fashion as the corresponding parameter of cmdBeginRenderPass.

-> io () 

vkCmdNextSubpass - Transition to the next subpass of a render pass

Description

The subpass index for a render pass begins at zero when cmdBeginRenderPass is recorded, and increments each time cmdNextSubpass is recorded.

Moving to the next subpass automatically performs any multisample resolve operations in the subpass being ended. End-of-subpass multisample resolves are treated as color attachment writes for the purposes of synchronization. This applies to resolve operations for both color and depth/stencil attachments. That is, they are considered to execute in the PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT pipeline stage and their writes are synchronized with ACCESS_COLOR_ATTACHMENT_WRITE_BIT. Synchronization between rendering within a subpass and any resolve operations at the end of the subpass occurs automatically, without need for explicit dependencies or pipeline barriers. However, if the resolve attachment is also used in a different subpass, an explicit dependency is needed.

After transitioning to the next subpass, the application can record the commands for that subpass.

Valid Usage

  • The current subpass index must be less than the number of subpasses in the render pass minus one
  • This command must not be recorded when transform feedback is active

Valid Usage (Implicit)

  • contents must be a valid SubpassContents value
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics operations
  • This command must only be called inside of a render pass instance
  • commandBuffer must be a primary CommandBuffer

data ImageCopy Source #

VkImageCopy - Structure specifying an image copy operation

Description

For IMAGE_TYPE_3D images, copies are performed slice by slice starting with the z member of the srcOffset or dstOffset, and copying depth slices. For images with multiple layers, copies are performed layer by layer starting with the baseArrayLayer member of the srcSubresource or dstSubresource and copying layerCount layers. Image data can be copied between images with different image types. If one image is IMAGE_TYPE_3D and the other image is IMAGE_TYPE_2D with multiple layers, then each slice is copied to or from a different layer.

Copies involving a multi-planar image format specify the region to be copied in terms of the plane to be copied, not the coordinates of the multi-planar image. This means that copies accessing the R/B planes of “_422” format images must fit the copied region within half the width of the parent image, and that copies accessing the R/B planes of “_420” format images must fit the copied region within half the width and height of the parent image.

Valid Usage

  • The number of slices of the extent (for 3D) or layers of the srcSubresource (for non-3D) must match the number of slices of the extent (for 3D) or layers of the dstSubresource (for non-3D)

data BufferImageCopy Source #

VkBufferImageCopy - Structure specifying a buffer image copy operation

Description

When copying to or from a depth or stencil aspect, the data in buffer memory uses a layout that is a (mostly) tightly packed representation of the depth or stencil data. Specifically:

Note

To copy both the depth and stencil aspects of a depth/stencil format, two entries in pRegions can be used, where one specifies the depth aspect in imageSubresource, and the other specifies the stencil aspect.

Because depth or stencil aspect buffer to image copies may require format conversions on some implementations, they are not supported on queues that do not support graphics.

When copying to a depth aspect, and the VK_EXT_depth_range_unrestricted extension is not enabled, the data in buffer memory must be in the range [0,1], or the resulting values are undefined.

Copies are done layer by layer starting with image layer baseArrayLayer member of imageSubresource. layerCount layers are copied from the source image or to the destination image.

For purpose of valid usage statements here and in related copy commands, a blocked image is defined as:

  • a image with a single-plane, “_422” format, which is treated as a format with a 2 × 1 compressed texel block, or
  • a compressed image.

Valid Usage

  • bufferRowLength must be 0, or greater than or equal to the width member of imageExtent
  • bufferImageHeight must be 0, or greater than or equal to the height member of imageExtent
  • The aspectMask member of imageSubresource must only have a single bit set

Valid Usage (Implicit)

See Also

DeviceSize, Extent3D, ImageSubresourceLayers, Offset3D, cmdCopyBufferToImage, cmdCopyImageToBuffer

Constructors

BufferImageCopy 

Fields

  • bufferOffset :: DeviceSize

    bufferOffset is the offset in bytes from the start of the buffer object where the image data is copied from or to.

  • bufferRowLength :: Word32

    bufferRowLength and bufferImageHeight specify in texels a subregion of a larger two- or three-dimensional image in buffer memory, and control the addressing calculations. If either of these values is zero, that aspect of the buffer memory is considered to be tightly packed according to the imageExtent.

  • bufferImageHeight :: Word32
     
  • imageSubresource :: ImageSubresourceLayers

    imageSubresource is a ImageSubresourceLayers used to specify the specific image subresources of the image used for the source or destination image data.

  • imageOffset :: Offset3D

    imageOffset selects the initial x, y, z offsets in texels of the sub-region of the source or destination image data.

  • imageExtent :: Extent3D

    imageExtent is the size in texels of the image to copy in width, height and depth.

data RenderPassBeginInfo (es :: [Type]) Source #

VkRenderPassBeginInfo - Structure specifying render pass begin info

Description

renderArea is the render area that is affected by the render pass instance. The effects of attachment load, store and multisample resolve operations are restricted to the pixels whose x and y coordinates fall within the render area on all attachments. The render area extends to all layers of framebuffer. The application must ensure (using scissor if necessary) that all rendering is contained within the render area. The render area, after any transform specified by RenderPassTransformBeginInfoQCOM::transform is applied, must be contained within the framebuffer dimensions.

If render pass transform is enabled, then renderArea must equal the framebuffer pre-transformed dimensions. After renderArea has been transformed by RenderPassTransformBeginInfoQCOM::transform, the resulting render area must be equal to the framebuffer dimensions.

When multiview is enabled, the resolve operation at the end of a subpass applies to all views in the view mask.

Note

There may be a performance cost for using a render area smaller than the framebuffer, unless it matches the render area granularity for the render pass.

Valid Usage

  • clearValueCount must be greater than the largest attachment index in renderPass that specifies a loadOp (or stencilLoadOp, if the attachment has a depth/stencil format) of ATTACHMENT_LOAD_OP_CLEAR

The array is indexed by attachment number. Only elements corresponding to cleared attachments are used. Other elements of pClearValues are ignored.
